28. AQS 1, Zhejiang PM2.5 Test Data
R2 = 0.78

29. Factory calibration Calibration is a significant production cost.
Slope and intercept variation distributed around 1 and 0 with a normal distribution.
Tradeoff: time vs accuracy. Existing process for O3:
sd at zero = 2 ppb
sd of slope = 0.03

30. Calibration process Sensors are batch calibrated.
Each sensor has its own individual calibration uploaded and stored in onboard memory
Slope and zero follow a normal distribution and acceptance is determined by +/- 1 σ. For O3 calibration
σslope < 0.03
σzero < 2 ppb
